Critical physiological events throughout the body are controlled by extracellular signals from neurotransmitters and hormones acting on cell surface receptors. Receptors transduce these signals to alter intracellular metabolism and cellular responsiveness through heterotrimeric G protein/second messenger pathways or through small GTP-binding protein/protein kinase cascades. The mechanisms that control the responsiveness of target organ G protein-coupled receptors include receptor ph
